The guide plate 214 is tilted. The inclined surface of the guide plate 214 is adapted to the bottom surface of the sorting plate 213, so that when the sorting plate 213 is attached to the guide plate 214, the sorting plate 213 will keep the tablets on the guide plate 214 and cannot slide off.
[0040] Furthermore, the material box 215 is located below the guide plate 214, so that the tablets sliding down the guide plate 214 fall into the material box 215. The material box 215 below the guide plate 214 contains material boxes 215 corresponding to tablets with larger weight, tablets with smaller weight, and qualified tablets. The material boxes 215 below the guide plate 214 are evenly distributed in a straight line. The material box 215 for crushed tablets is adjacent to the guide plate 214. A funnel 216 is fixedly installed on the body 1. The top of the funnel 216 is adjacent to the weight sorting detector 27, and the bottom of the funnel 216 is located above the material box 215 for crushed tablets.
[0041] Among them, when sorting is performed, the vibrating disk 21 is started. The vibrating disk 21 arranges the tablets conveyed to the sorting device and sends the arranged tablets onto the vibrating track 22. Then the vibrating motor 23 is started. The vibrating motor 23 drives the vibrating track 22 to vibrate, causing the tablets on the vibrating track 22 to move. Then the vacuum suction head 26 is started. The vacuum suction head 26 sucks the tablets on the vibrating track 22 and sends them to the weight sorting detector 27. After detection, the vacuum suction head 26 sends the tablets to the guide plate 214 or sends the broken tablets into the funnel 216. At the same time, the vacuum suction head 26 re-carries a tablet from the vibrating track 22 to the weight sorting detector 27. Meanwhile, the electric control telescopic rod 212 is started. The electric control telescopic rod 212 drives the sorting plate 213 to abut against the guide plate 214, so that the sorting plate 213 blocks the tablets on the guide plate 214. Then the stepping motor 211 is started. The stepping motor 211 drives the screw rod 210 to rotate. The screw rod 210 drives the carriage 29 to move on the slide rail 28, so that the sorting plate 213 drives the tablets to move to the corresponding qualified (overweight, underweight) material boxes 215. The sorting plate 213 resets, causing the tablets to slide off the guide plate 214.
[0042] Embodiment 3, as Figures 5 - 8 shown, the difference from the above embodiment is that the auxiliary mechanism 3 further includes a connecting frame 31. A plurality of connecting frames 31 are fixedly installed on the central frame 24. The connecting frames 31 are respectively located above each of the material boxes 215 below the guide plate 214.

The receiving trays 32 are located above the material boxes 215. The top ends of the connecting frames 31 are all fixedly installed with first servo motors 33. The first servo motors 33 are all power-connected to the receiving trays 32.
[0043] Furthermore, the bottom end of the receiving tray 32 is an open end. The bottom ends of the receiving trays 32 are all rotatably fitted with rotating plates 34. The rotating plates 34 are adapted to the bottom ends of the receiving trays 32. Second servo motors 35 are fixedly installed on the receiving trays 32. The second servo motors 35 are power-connected to the rotating plates 34. Cameras 36 are fixedly installed on the connecting frames 31. The cameras 36 are located above the receiving trays 32. The cameras 36 are used for photographing and analyzing the fragmentation of the tablets. A plurality of discharge limiting grooves 37 are fixedly installed at the bottom end of the guide plate 214. The bottom ends of the discharge limiting grooves 37 are located directly above the receiving trays 32.
[0044] Furthermore, a suspension 38 is fixedly mounted on the center frame 24, and the suspension 38 is adjacent to the receiving plate 32. The suspension 38 extends above the material box 215 where the crushed tablets are placed. A plurality of conveying rollers 39 are rotatably engaged on the suspension 38, and a conveyor belt 310 is tensioned on the conveying rollers 39. A conveying motor 311 is fixedly mounted on the suspension 38, and the conveying motor 311 is power-connected to the conveying rollers 39. The conveyor belt 310 is used to convey the re-crushed tablets to the material box 215 where the crushed tablets are placed.
[0045] Among them, as the tablets slide on the guide plate 214, the tablets fall into the discharge limit groove 37, and the discharge limit groove 37 sends the tablets into the receiving tray 32, and the camera 36 is started. The camera 36 takes a picture of the tablets and makes a judgment. When the tablets are not broken again, the second servo motor 35 is started, and the second servo motor 35 drives the rotating plate 34 to rotate, so that the tablets fall from the receiving tray 32 into the material box 215. When the tablets are broken again, the first servo motor 33 is started, and the first servo motor 33 drives the receiving tray 32 to rotate, so that the receiving tray 32 rotates to the top of the conveyor belt 310, and the conveying motor 311 is started. The conveying motor 311 drives the conveying roller 39 to rotate, and the conveying roller 39 drives the conveyor belt 310 to rotate, so that the conveyor belt 310 sends the broken tablets into the material box 215 where the broken tablets are placed.
[0046] The overall working principle of the sorting equipment:
[0047] The tablets are transported to the weight sorting detector 27 for detection. After the detection, the tablets are sorted into various material boxes 215, so that qualified tablets are sorted into one material box 215, tablets with relatively large weight are sorted into one material box 215, tablets with relatively small weight are sorted into one material box 215, and broken unqualified tablets are sorted into one material box 215. Before the tablets fall into the material box 215, they will first fall onto the receiving tray 32. The sorted tablets are again tested for fragmentation on the receiving tray 32, so that the tablets that are broken again during the transmission process after sorting are sent to the conveyor belt 310 by the receiving tray 32. The conveyor belt 310 transports the broken tablets to the material box 215 where the broken unqualified tablets are placed, so that the tablets are broken and distinguished again before sorting and collection, ensuring that the sorted tablets are complete and accurate, improving the processing quality of the sorting equipment, and improving the stability of the operation of the sorting equipment;
[0048] Among them, when sorting treatment is carried out, the vibrating disk 21 is started. The vibrating disk 21 arranges the tablets conveyed to the sorting device and sends the arranged tablets onto the vibrating track 22. Then the vibrating motor 23 is started. The vibrating motor 23 drives the vibrating track 22 to vibrate, causing the tablets on the vibrating track 22 to move. Then the vacuum suction head 26 is started. The vacuum suction head 26 adsorbs the tablets on the vibrating track 22 and sends them to the weight sorting detector 27. After detection, the vacuum suction head 26 sends the tablets onto the guide plate 214 or sends the broken tablets into the funnel 216. At the same time, the vacuum suction head 26 re-carries a tablet from the vibrating track 22 to the weight sorting detector 27. Meanwhile, the electric control telescopic rod 212 is started. The electric control telescopic rod 212 drives the sorting plate 213 to abut against the guide plate 214, so that the sorting plate 213 blocks the tablets on the guide plate 214. Then the stepping motor 211 is started. The stepping motor 211 drives the screw rod 210 to rotate. The screw rod 210 drives the carriage 29 to move on the slide rail 28, so that the sorting plate 213 drives the tablets to move to the corresponding qualified (overweight, underweight) material boxes 215. The sorting plate 213 resets, causing the tablets to slide off the guide plate 214;
[0049] As the tablets slide off the guide plate 214, the tablets fall into the discharge limit slot 37. The discharge limit slot 37 sends the tablets into the receiving tray 32. The camera 36 is started. The camera 36 takes pictures of the tablets for judgment. When the tablets are not broken again, the second servo motor 35 is started. The second servo motor 35 drives the rotating plate 34 to rotate, so that the tablets fall from the receiving tray 32 into the material box 215. When the tablets are broken again, the first servo motor 33 is started. The first servo motor 33 drives the receiving tray 32 to rotate, so that the receiving tray 32 rotates above the conveyor belt 310. The conveyor motor 311 is started. The conveyor motor 311 drives the conveyor roller 39 to rotate. The conveyor roller 39 drives the conveyor belt 310 to rotate, so that the conveyor belt 310 sends the broken-again tablets into the material box 215 for placing the broken tablets.
